NXP LPC

LPC (Low Pin Count) is a family of 32-bit microcontroller integrated circuits by NXP Semiconductors (formerly Philips Semiconductors). The LPC chips are grouped into related series that are based around the same 32-bit ARM processor core, such as the Cortex-M4F, Cortex-M3, Cortex-M0+, or Cortex-M0. Internally, each microcontroller consists of the processor core, static RAM memory, flash memory, debugging interface, and various peripherals. The earliest LPC series were based on the Intel 8-bit 80C51 core. As of February 2011, NXP had shipped over one billion ARM processor-based chips.

Overview
All recent LPC families are based on ARM cores, which NXP Semiconductors licenses from ARM Holdings, then adds their own peripherals before converting the design into a silicon die. NXP is the only vendor shipping an ARM Cortex-M core in a dual in-line package: LPC810 in DIP8 (0.3-inch width) and LPC1114 in DIP28 (0.6-inch width). The following tables summarize the NXP LPC microcontroller families.

LPC
All LPC microcontrollers have a ROM'ed bootloader that supports loading a binary image into its flash memory using one or more peripherals (varies by family). Since all LPC bootloaders support loading from the UART peripheral and most boards connect a UART to RS-232 or a USB-to-UART adapter IC, thus it's a universal method to program the LPC microcontrollers. Some microcontrollers requires the target board to have a way to enable/disable booting from the ROM'ed bootloader (i.e. jumper / switch / button).
 * Flash programming via UART
 * lpc21isp A multi-platform open-source tool to flash LPC microcontrollers over the UART.
 * Flash Magic, a commercial program for Windows and macOS to perform in-system programming of the LPC flash via its UART.
 * nxp_isp_loader, an open-source tool to flash LPC microcontrollers over the UART.


 * Debugging tools (JTAG / SWD)
 * OpenOCD, an open source software package for JTAG access using a wide variety of hardware adapters.
 * LPC-Link 2, by NXP, a JTAG / SWD debug adapter that has multiple firmware releases available to emulate popular debug adapter protocols, such as: J-Link by Segger, CMSIS-DAP by ARM, Redlink by Code Red Technologies. All connectors are 1.27 mm (0.05-inch) pitch.

Documentation
The amount of documentation for all ARM chips is daunting, especially for newcomers. The documentation for microcontrollers from past decades would easily be inclusive in a single document, but as chips have evolved so has the documentation grown. The total documentation is especially hard to grasp for all ARM chips since it consists of documents from the IC manufacturer (NXP Semiconductors) and documents from CPU core vendor (ARM Holdings).

A typical top-down documentation tree is: manufacturer website, manufacturer marketing slides, manufacturer datasheet for the exact physical chip, manufacturer detailed reference manual that describes common peripherals and aspects of a physical chip family, ARM core generic user guide, ARM core technical reference manual, ARM architecture reference manual that describes the instruction set(s).
